The functions I need are:
- Product list in the cart (image, quantity, price, product URL)
- Add product to the cart
- Change quantity produced in the cart
- Delete product from the cart
- check shipping data entered (answer possible ok or ko. If ko, motivation)
- any "shipping costs" (may change to any address change), "any discounts", "any extra costs"
- order conclusion (payment will be made via an external gateway to the site, which will return: "outcome ok" or "ko outcome". If "ok outcome", then you must communicate to the shop that the order is complete and paid and the Shipping address must also be sent).
These fuers must be called Tramity an "endpoint", recalled via Ajax.
All "Return" Delel functions must be "JSON"
The request is very urgent and very tight times.
